Tiny room with good Wi-Fi wanted

We're a not-for-profit based on Tanner Street SE1. We're currently launching a new service and require a local small room in which to run hour-long video consultations. We only need enough private space for one person and a laptop, with Wi-Fi strong enough to run calls on software similar to Skype.

Ideally we'd like somewhere with an hourly rate that we can hire on an ad-hoc basis between now and April 2013.

If you have anything that sounds suitable or any suggestions for me to try I'd be most grateful to hear from you.

I wonder if we might be of help. We have a space at 61 Southwark Street - the light here on the 6th floor is really great and we have a few small rooms that I am sure would be perfect. And we charge by the hour - from £12 per hour. If you are interested please do let me know and we can show you around. We are open Mon-Fri from 0830 - 1800 and tonight there will be somebody here much later than that as we have an event on.

We have a meeting space available for upto 4 people.
It is recently been refurbished and is 300cm by 400cm.
We currently rent out at £50 + VAt for half a day or £100 + VAT for full day. Please let me know if you would like to arrange a viewing.Tel 0207 403 1500 and ask for Sema. Thanks
